While researching a topic for my book I cam across the original paper that helped spawn the concept of Yesterday's Weather. That is the probability that amount of work you will do next week is highly likely to be the same as the amount of work you did last week.

Abstract

In this study, the authors used 111 time series to examine the accuracy of various forecasting methods, particularly time-series methods. The study shows, at least for time series, why some methods achieve greater accuracy than others for different types of data. The authors offer some explanation of the seemingly conflicting conclusions of past empirical research on the accuracy of forecasting. One novel contribution of the paper is the development of regression equations expressing accuracy as a function of factors such as randomness, seasonality, trend-cycle and the number of data points describing the series. Surprisingly, the study shows that for these 111 series simpler methods perform well in comparison to the more complex and statistically sophisticated ARMA models.

devZing has a good post on how to delete bugs in Bugzilla.

All Bugzilla instances have been updated to 3.4.6. You can read about all the changes here or just the differences below.

• When doing a search that involves "not equals" or "does not contain the string" or similar "negative" search types, the search description that appears at the top of the resulting bug list will indicate that the search was of that type. (Bug 474738)
• In Internet Explorer, users couldn't easily mark a RESOLVED DUPLICATE bug as REOPENED, due to a JavaScript error. (Bug 546719)
• If you use a "bookmarkable template" to pre-fill forms on the bug-filing page, and you have custom fields that are only supposed to appear (or only supposed to have certain values) based on the values of other fields, those custom fields will now work properly. (Bug 538211)
• If you have a custom field that's only supposed to appear when a bug's resolution is FIXED, it will now behave properly on the bug-editing form when a user sets the bug's status to RESOLVED. (Bug 520993)
• If you are logged-out and using request.cgi, the Requester and Requestee fields no longer respect the usermatching parameter--they always require full usernames. (Bug 533018)
• If you tried to do a search with too many terms (resulting in a URL that was longer than about 7000 characters), Apache would return a 500 error instead of your search results. (Bug 513989)
• Bugzilla would sometimes lose fields from your sort order when you added new fields to your sort order. (Bug 470214)
• The Atom format of search results would sometimes be missing the Reporter or Assignee field for some bugs. (Bug 537834)

All Bugzilla instances have been updated to 3.4.5 in order to resolve a security issue announced yesterday.

All Bugzilla instances have been updated to 3.4.4 in order to resolve a security issue announced yesterday.

The Consultants Guild is excited to announce the first of several hosted services.

Our first service is the widely used and extremely popular Bugzilla.

Bugzilla is a "Defect Tracking System" or "Bug-Tracking System". Defect Tracking Systems allow individual or groups of developers to keep track of outstanding bugs in their product effectively.

Our hosted Bugzilla service will provide you with your own instance of which you will be the administrator. You can then choose whether or not your instance will be public or private, as well as all the standard Bugzilla options.

Pricing is as little as $10/month and there is a 14 day free trial, no credit card required.
